The system comprises a first substantially annular seat (159) provided in a first wall (155A) defined by the first mechanical element (155); and a second substantially annular seat (161 A, 161B) provided in a second wall (153A) defined by the second mechanical element (1). When the two mechanical elements are assembled the second substantially annular seat is positioned approximately at the level of the first substantially annular seat and the second wall is inside the first wall. The connection system between the mechanical elements also comprises at least one filiform element (157) forming a member for reciprocal blocking of the two mechanical elements, which is inserted in a space defined by the two opposed annular seats. Moreover, there is also provided a forcing member (173), insertable in a space defined between two opposed surfaces belonging respectively to the first and to the second mechanical element.
